Troubleshooting Zapier REST Hook Subscription Issues

Hey everyone, I’m stuck with a Zapier REST Hook subscribe problem. The auth setup is fine, but something weird is happening.

When Zapier sends the POST subscribe with target_url and event info, it’s all good. But as soon as I try to POST data to that target_url, the unsubscribe url gets called out of nowhere. This kills the target_url, so any POST or GET requests just get a ‘please unsubscribe me!’ message.

I’ve triple-checked everything, but I can’t figure out why this is happening. Has anyone run into this before? Any tips or tricks would be super helpful!

Here’s a quick example of what I’m working with:

# Zapier subscribe response
subscribe_response = {
    'hook_url': 'https://hooks.example.com/abc123',
    'target_url': 'https://hooks.example.com/abc123',
    'trigger': 'new_user_signup'
}

# Trying to post data
user_data = {
    'name': 'Alice Smith',
    'email': '[email protected]',
    'trigger': 'new_user_signup'
}

# But this causes an unsubscribe. Why?
response = requests.post(subscribe_response['target_url'], json=user_data)

Any ideas on what might be causing this automatic unsubscribe? Thanks in advance!

I’ve encountered a similar issue before. It’s worth investigating if there’s any middleware or security layer in your application that might be interfering with the webhook process. Sometimes, certain security configurations can misinterpret incoming POST requests and trigger unintended actions. Additionally, ensure that your server is correctly parsing and handling the incoming JSON payload from Zapier. Double-check your server logs for any error messages or unexpected behavior when receiving the POST request. If the problem persists, you might want to implement detailed logging for each step of the webhook process to pinpoint exactly where the unsubscribe is being triggered.

hey josephk, try checking if your payload fields match zapier’s expected ones exactly. sometimes minor mismatches cause troubles. also, verify the webhook settings for possible timeouts. hope that helps!

I ran into a similar headache with Zapier webhooks a while back. What fixed it for me was adding a custom header to my POST requests. Zapier sometimes expects a specific header to validate the incoming data. Try something like this:

headers = {‘X-Zapier-Webhook-Secret’: ‘your_secret_here’}
response = requests.post(subscribe_response[‘target_url’], json=user_data, headers=headers)

Also, double-check your Zapier trigger setup. Make sure you’re not accidentally setting any conditions that could trigger an unsubscribe. It’s easy to overlook a setting there.

If that doesn’t work, try implementing some logging on your server side to track the exact flow of requests. It might reveal something unexpected in the process. Good luck troubleshooting!
